The JBL Aquaristik and Terraristik CO2 fertilization system is a highly developed solution for automatic CO2 fertilization in freshwater aquariums. It is specifically designed for aquariums with a volume of 40 to 600 liters and ensures optimal CO2 supply for plants, promoting their growth and health. The system includes a pressure regulator with a solenoid valve, a CO2/pH computer, a bubble counter with a check valve, and a CO2 reactor. The precise regulation of CO2 supply is automatically managed by the CO2/pH controller, which measures the pH level and adjusts the CO2 amount accordingly. This guarantees that plants always receive the ideal CO2 supply. Installation is straightforward and only requires connection to a CO2 cylinder, which must be purchased separately. The system is made of durable plastic and provides a reliable solution for fertilizing aquarium plants.
